Ground Source Heating and Cooling
Category: Alternative Supply Systems, Energy Supply
Ground source heating and cooling, or geoexchange, is a technique that utilizes geothermal energy to heat or cool buildings, depending on the season. Ground temperatures are relatively consistent, varying on latitude rather than season. A series of underground pipes and water, a building can exchange the temperature from the ground to provide a baseline temperature that is cooler than the air in the summer and warmer than the outside air in the winter. This baseline temperature provided to the building reduces the energy needed to heat or cool the building to comfortable temperatures.
- Energy consumption can drop nearly 50% with the installation of a geothermal heating/cooling system.
- Geoexchange systems have a lifespan of 50+ years
- Climate and ground temperature can impede the efficiencies of a geoexchange system.
- Geoexchange systems require a large amount of land to drill wells.
Energy consumption is greatly reduced for each building fitted with a geo-exhange system.
